Lithuanian survey shows 76% support advisory referendum on defining family in constitution

A new public opinion poll reveals that 76% of Lithuanians support holding an advisory referendum to enshrine a traditional definition of family in the country’s constitution, LRT reports.

The survey, conducted by Baltijos Tyrimai for the Free Society Institute between April 23 and May 7, found broad backing for a constitutional amendment stating that legal family relations arise only from marriage between a man and a woman, as well as from motherhood and fatherhood.

Of those polled, 41% strongly supported the referendum, while 35% expressed partial support. Opposition stood at 16%, with 8% undecided.

Support crossed demographic lines, ranging from 73% to 83% across gender, age, income, and location. Even among younger respondents (18–29), 65% backed the proposal, compared to 18% opposed. Rural and small-town residents showed the highest approval, though nearly three-quarters of city dwellers also supported the measure.

The poll also found consistent support regardless of marital status, with 78% of married and 86% of divorced respondents in favor. Among single individuals, 63% supported the referendum—three times the opposition rate (21%).

Political affiliation influenced responses, with the strongest backing from supporters of the conservative Homeland Union (73%), the Liberal Movement (78%), and the Farmers and Greens Union (82%). Even among undecided voters, 66% favored the referendum.

The nationally representative survey included 1,000 adults and had a margin of error of 3.1% at a 95% confidence level.
